RETURN-FLOW SYRINGE.

SPECIFICATION forming part of Letters Patent No. 676,269, dated June 11,1901.

llpplication filed December 14, 1900. Serial Non 89,897. (No model.)

To aZZ whom it may concern.-

Be it known that I, DENWOOD N. L. NEW- BURY, a citizen of the UnitedStates, and a resident of the city of New York, borough of Manhattan, inthe county and State of New York, have invented a new and ImprovedReturn- Flow Syringe, of which the followingis a full, clear, and exactdescription.

The purpose of the invention is to construct an irrigating vaginalsyringe in such manner that it may be as safely and satisfactorily usedby a patient as by a physician, and also to so construct the device thatit will not become foul and so that all portions of the vaginal canalmay be reached, likewise the mouth of the womb.

The main objects sought to be attained by the use of the irrigatingvaginal syringe are as follows: the treatment of all chronic womb andovarian troubles by the prolonged use of plain hot or medicated water,the treatment of any local trouble in the vagina, and to provide forcleanliness of the genital parts.

To render the above possible, it is necessary to construct an instrumentwhose line of direction conforms to that of the vaginal canal and aninstrument that conforms to the different diameters of the vaginalcanal, so as to keep its walls on the stretch and render it possible toreach every part of its inner surface. The instrument should also beprovided with a centrally-located irrigating-core, which which will notonly throw streams against the entire vaginal canal, but also from itsinner end against the mouth of the womb. In connection with thecentrally-located core an open-wire shield should be provided which willpermit not only the irrigation of the entire vaginal canal, but also theexternal genitals. The device should also be provided with a discharge-receptacle of a character which permits the entire process to be madeclean and dry to all the external parts.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both figures.

Figure 1 is a perspective view of the device,

and Fig. 2 is a longitudinal vertical section through the same.

A central tube A is employed in the construction of the device, and theouter end 10 of the said tube is upturned and provided with anenlargement 11, over which a rubber tube may he slipped and held. Thismain tube A of the device is provided witha series of apertures 12,ranging from a point near the upturned portion 10 to the inner end ofthe tube, and at the inner end of the tube a plate 13 is located, whichcloses the said inner end to some extent; but the said plate 13 isprovided with apertures 14:,wl1ich,with the apertures 12, permit theescape of liquid in certain quantities not only from the side portionsof the main tube A, but from the inner end of the same. 13 is usuallysecured to a collar 15, into which collar the inner end of the main tubeA is screwed or otherwise secured.

In connection with the main tube A a shield Bis employed. The frontportion of the shield is in form of a loop 16, and the said shield ismade from wire of suitable gage or from bar metal, and the loop-section16 at the front of the shield receives the outer end of the main tube A,the said tube passing out usually through about the central portion ofthe loop, and the upwardly-extending portioulO of the main tube is infront of the loop. The front portion of the shield B also comprises ahandle 17, which is a continuation of the loop, and the said handle 17has more or less of an outward inclination from the loop 16, as shown inFig. 2. The inner face of the loop 16 and of the handle 17 is concavedand the outer face of said loop and said handle is convexed.

The body portion of the shield B consists of a series of bars or wires18, which at their inner ends are attached to or made integral with theperforated cap-plate 13. The outer ends of the wires or bars 18 aregiven an outward inclination and are attached to the side portions ofthe loop 16.

The shield B and the main tube A are in a line of direction conformingto that of the vaginal canal, and the body portion of the shield B, orthat portion which surrounds the fenestrated tube A, conforms to thedifierent diameters of the vaginal canal. To this end the wires, rods,or bars 18, forming the skele- This apertured cap-plate ton body of theshield, are bowed outward near their inner ends, and the inner ends ofthe wires, rods, or bars of the body of the shield are made exceedinglysmooth where they meet the cap-plate 13.

The outwardlybowed portion of the body of the shield is desi gnated asO, and where the body of the shield approaches the front portion,section, or loop 16 the wires, rods, or bars are curved in di rection ofthe main tube A, as shown at O. The outer portion of the main tube A issup ported, preferably, by a bracket 19, which is provided at itscentral portion with a dropsection receiving the main tube A, and theends of this bracket are secured in any suit,- able or approved mannerto the sides of the loop 16.

' A receptacle 20 is secured in any suitable or approved manner to'thefront lower portionof the loop-section 16 of the shield B. Thisreceptacle is located below the forwardlyextending portion of the maintube A to a greater or less extent, and the said receptacle 20 ispreferably contracted at its lower portion and at its lower end isprovided with an outlet-neck 21, having a suitable enlargement toreceive and hold a rubber tube in place, which tube may be conducted toa convenient basin.

In the operation of this device when it is introduced into the vaginalcanal the body portion of the shield and the main portion of the maintube A are within the canal, and

r Y the body portion of the shield conforms to the different diametersof the Vaginal canal and stretches the wall thereof. The liquid which issupplied to the main tube A will find an exit through the side openings12 and through the end openings'14, the streams or jets from the sideopenings 12 reaching the wall of the vaginalcanal, while the streams orjets from the openings 14 reach the mouth of the womb. The front portionor loop 16 of the shield engages with the front of the body and does notinterfere with the treatment of the outer genital parts,- and the handle17 may be held close to the abdomen and the instrument or devicethusheld in place. The vaginal canal constitutes a conductor for the fluidintroduced therein, and such fluid is delivered into the receptacle 20,from whence it finds its way to the basin referred to or to any otherreceptacle placed to receive it.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination with a tube having apertures inits sides, of a shield within which the tube is contained, the saidshield comprising a body-section consisting of a series of curved bars,and a front section in the form .said tube extending upward, andenlarged at its extremity, ofa shield within which the tube is containedand comprising a body-section consisting of a series of curved barsconnected at their inner ends with the perforated cap-plate at the innerend of the tnbe, and a front portion in the form of a loop with whichthe other ends of the said bars are connected, the said front portion orloop terminating at its upper end in a handle portion, the outer end ofthe tube extending forward through the loop portion, and theupwardly-extending end of said tube being located in front of the loop,a bracket connected with the sides of the loop portion for supportingthe outer portion of the tube, and a receptacle secured to'the frontlower portionof the loop and located go below theforwardly-extendingportion of thesaid tube, substantially as shown anddescribed.

3. In a syringe, the combination with a tube having apertures in itssides, the said tube having an upturned outer end, of a shieldcomprisinganupwardly-extendingfrontloopsection through which the outerend of the tube extends, and a body-section comprising a series of barsconnected at one end with the too inner end of the tube and at the otherend with the loop-section of the shield, the bars having an outwardinclination where they connect with the loop-section, the body of theshield being also convexed at the inner end portion of the tube andconcaved and reduced in diameter at a point adjacent to theloop-section, a support for the outer portion of the tube carried by theloop-section, and a receptaclecarried by the lower portion of the loop-1 10 section, the upturned end of the tube extending in front of theloop-section, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
